Isabel Briggs Myers

Isabel Briggs Myers (18 October 1897 – May 5, 1980[1][2]) was an American psychological theorist. She was co-creator, with her mother (Katharine Cook Briggs, January 3, 1875[3] – 1968), of the Myers-Briggs Type Indicator (MBTI).

She was home-schooled by her mother and went on to earn a bachelor's degree in political science from Swarthmore College. The mother read Carl Jung's book, Psychological Types and recommended it to Myers; they then formulated the MBTI together. Later in life, she collaborated with Mary McCaulley to conduct tests of her research and of the MBTI.

Myers wrote a prize-winning mystery novel, Murder Yet to Come, in 1929, using typological ideas. She also wrote second book, Gifts Differing.
